1092 Warm Line

The warm line capability is a Central Office switch based automatic 
dialing feature.

If an ESP's client with a warm line capability goes off-hook and commences
dialing within the time delay period, the call will proceed normally as
dialed.  If dialing has not started before the end of the time delay
period, a stored number is automatically dialed.

FEATURE OPERATION:
1. A subscriber of this service, upon going off-hook to initiate an outgoing 
   call has the option to either:
   a. Dial the call in the normal manner OR
   b. Wait for the prespecified time delay period and have the call 
      automatically dialed to a single predetermined number OR
   c. If calling from a Touch-Tone phone, dial the # to immediately activate the
      automatic dialing.

2. The service, including the time delay interval and the predetermined number,
   is initially activated via a service order with the telephone company.

3. Subsequent changes to the time delay interval may only be made via a 
   telephone company service order.  Changes to the predetermined number may be
   made via a telephone company service order or, as an option, be made from the
   subscriber's line in the following manner:
   a. Listen for dial tone.
   b. Dial a telephone company assigned update code and receive second dial tone
      after a four second pause (subscribers with Touch-Tone lines can avoid 
      this pause by dialing # after the update code).
   c. Dial the new number.  After a short time-out period, the new number will 
      be active.

   If the above described option is available, the service can be deactivated
   by following the same procedure but not dialing in a new number.  To
   reactivate the service, the subscriber would again follow the above described
   procedure and must re-enter the predetermined number.
